156 THE CANADIAN ENTOMOLOGIST. 



bands expand somewhat on the costal and inner borders. On the fore 

 wings of most of the males are scattered scales of a straw yellow color, 

 especially bordering the oblique bands ; fringes of the fore wings lighter 

 in the middle, but at the apex and anal angle concolorous with the oblique 

 bands. 



Hind wings above, with their fringes, as well as the abdomen above 

 and the under side of fore wings, fuscous. Under side of hind wings and 

 legs lighter. 



Expanse — $ 15-20 m. m. ; $ 20-26 m. m. 



Habitat— Mass., N. Y., Ontario, Ohio, Wis. 



Described from eleven males and fifteen females. 



Raised by James Angus, of West Farms, N. Y., on Hickory leaves. 



Penthina osmitinhma, n. s. 



Front of the head and first two joints of the palpi, light ochre yellow ; 

 last joint of the palpi, two spots on the outside of the middle joint of the 

 palpi, vertex, thoracic tuft and an edging of scales around the patagia, dark 

 purple ; front of thorax dark reddish brown with violet reflections in 

 certain lights. 



Fore wings dark reddish brown with a large reddish yellow subtri- 

 angular spot, the base resting upon and occupying the middle half of the 

 hinder border of the wing, while the opposite angle extends nearly to the 

 costa. The basal patch has numerous lead-blue metallic scales scattered 

 over it, showing a slight indication of an arrangement in cross lines in 

 some specimens, the outer edge beginning at the basal third of the costa, 

 extends directly across the wing as far as the middle of the cell, thence in 

 a more or less waved line across to the hind margin near the humeral 

 angle. This line is frequently indicated by whitish scales. From the 

 middle of the costa an interrupted double row of lead-blue metallic scales 

 extends obliquely across the wing towards the outer margin, confluent on 

 the disk, curving downward beyond and ending near the anal angle. 

 Numerous similarly colored scales rest upon the outside of the yellow 

 spot, and in a line curving up and outward join the previously described 

 line, leaving the ocellus quite free. On the costa beyond are three light 

 colored geminate spots faintly seen, from the inner one of which a lead- 

 blue line extends obliquely outward, and curving down, ends near the 

 middle of the outer margin. More or less black scales rest upon the 

 borders of these lines. Fringes fuscous, purple in one specimen.
